Error utilizando WMI
Buenos días,
he intentado utilizar el código que aparece en el artículo All about WiFi Networks and WiFi Adapters using the WMI and Delphi pero al ejecutar el procedimiento Current Wifi NetWork me da un error indicándome "clase no válida".
Project raised exception class EOleException with message "Clase no válida"
en la línea
Código:
FWbemObjectSet:= FWMIService.ExecQuery('SELECT * FROM WiFi_AdapterAssociationInfo','WQL',wbemFlagForwardOnly);
El código completo es el siguiente:
Código:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls,
ComObj, ActiveX, Variants, XPMan;
type
TForm1 = class(TForm)
Button1: TButton;
Memo1: TMemo;
XPManifest1: TXPManifest;
Button2: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure GetWiFi_AdapterAssociationInfo; //Current Wifi NetWork
const
WbemUser ='';
WbemPassword ='';
WbemComputer ='localhost';
wbemFlagForwardOnly = $00000020;
var
FSWbemLocator : OLEVariant;
FWMIService : OLEVariant;
FWbemObjectSet: OLEVariant;
FWbemObject : OLEVariant;
oEnum : IEnumvariant;
iValue : LongWord;
begin;
Form1.Memo1.Clear;
FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
FWMIService := FSWbemLocator.ConnectServer(WbemComputer, 'root\CIMV2', WbemUser, WbemPassword);
FWbemObjectSet:= FWMIService.ExecQuery('SELECT * FROM WiFi_AdapterAssociationInfo','WQL',wbemFlagForwardOnly);
oEnum := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant;
while oEnum.Next(1, FWbemObject, iValue) = 0 do
begin
Form1.Memo1.Lines.Add(Format('Associated %s',[FWbemObject.Associated]));// Boolean
Form1.Memo1.Lines.Add(Format('AuthenAlgorithm %s',[FWbemObject.AuthenAlgorithm]));// String
Form1.Memo1.Lines.Add(Format('AuthenEnabled %s',[FWbemObject.AuthenEnabled]));// Boolean
Form1.Memo1.Lines.Add(Format('AuthenMode %s',[FWbemObject.AuthenMode]));// String
Form1.Memo1.Lines.Add(Format('Caption %s',[FWbemObject.Caption]));// String
Form1.Memo1.Lines.Add(Format('Channel %s',[FWbemObject.Channel]));// String
Form1.Memo1.Lines.Add(Format('Description %s',[FWbemObject.Description]));// String
Form1.Memo1.Lines.Add(Format('Encryption %s',[FWbemObject.Encryption]));// String
Form1.Memo1.Lines.Add(Format('OpMode %s',[FWbemObject.OpMode]));// String
Form1.Memo1.Lines.Add(Format('Profile %s',[FWbemObject.Profile]));// String
Form1.Memo1.Lines.Add(Format('Rate %s',[FWbemObject.Rate]));// String
Form1.Memo1.Lines.Add(Format('SettingID %s',[FWbemObject.SettingID]));// String
Form1.Memo1.Lines.Add(Format('SSID %s',[FWbemObject.SSID]));// String
FWbemObject:=Unassigned;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
GetWiFi_AdapterAssociationInfo;
end;
end.
Utilizo Windows XP y Windows 7 y programo en Turbopascal.
¿Alguien puede ayudarme?
